Threaded Gradual On/Off Valves
Also known as gate valves, these valves gradually open and close to prevent system damage from suddenly starting and stopping flow.
Valves with a pull handle open and close faster than valves with a wheel handle. Also known as slide valves, they’re often used to control flow in air conditioning and ventilation systems.
Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

High-Pressure Threaded Gradual On/Off Valves
Designed for use in refineries and other demanding environments, these valves have a durable body that can withstand nearly twice the pressure of other gradual on/off valves. Also known as gate valves, they gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow.
These valves have a rising stem that lifts the handle as the valve opens and lowers as the valve closes. At a glance, you can see if flow is open or closed. The stem is isolated from what's flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. Their flanged stem housing, also known as a bolted bonnet, bolts in place to make them easy to take apart for maintenance and repairs. However, the flanged stem housing makes these valves heavier and larger than valves with threaded or welded stem housings.
Full-port valves do not restrict flow. Standard-port valves slightly restrict flow.
316 stainless steel valves have excellent corrosion resistance.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Bolt these valves to flanges. They gradually open and close to prevent system damage from suddenly starting and stopping flow.
Epoxy-coated cast iron valves are more corrosion resistant than plain cast iron or steel valves.
316 stainless steel valves have the best corrosion resistance.
Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than pull handles.
Pull handles open and close faster than wheel handles.
Nonrising stems stay in the same position whether the valve is open or closed. Valves with nonrising stems are often used underground and in other low-clearance locations.
Rising stems lift as the valve opens and lower as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a longer service life than valves with a nonrising stem.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Flanged Gradual On/Off Valves for Thick Liquids and Dry Materials
- Valve Type: Gate
- For Use With: Air, Argon, Deionized Water, Ethanol, Ethylene Glycol, Helium, Isopropyl Alcohol, Krypton, Methanol, Neon, Nitrogen, Salt Water, Soap Solutions, Water, Xenon
These valves have a sharp gate that slices through thick slurries, wastewater, dry bulk solids, and other materials that would clog other gradual on/off valves. They bolt to flanges and gradually open and close to prevent system damage from suddenly starting and stopping flow. The wheel handle opens and closes the valve with multiple turns, providing controlled, shock-resistant flow. The rising stem lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a long service life.

Vapor-Sealing Flanged Gradual On/Off Valves
- Valve Type: Gate
- For Use With: Gasoline, Oil, Steam, Water
- Specifications Met: API 602, ASME B16.34, MSS-SP-117
Control the flow of steam, hazardous gases, and other vapors without risking leaks. These valves have an accordion-like bellows around the stem that expands as they open and contracts as they close, forming an airtight seal. If the bellows fail, a reinforced seal—also known as a backseat seal—minimizes the risk of leakage. Ideal for heating and steam service applications, they maintain their seal even as the temperature swings. Plus, the stem housing is welded to make sure nothing leaks out. Also known as gate valves, these valves open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops. They bolt onto flanges, so they’re easier to install and remove for cleaning and repairs than threaded or weld-on valves.
The handle raises as these valves open and lowers as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.

High-Pressure Socket-Connect Gradual On/Off Valves
With a forged steel body and bolted construction, these valves can withstand nearly 10 times the pressure of other socket-connect gradual valves. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. Also known as gate valves, they gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow.
The handle raises as these valves open and lowers as they close to let you know if flow is on or off. The stem also raises when on so it doesn’t contact what’s flowing through your line. This gives these valves a longer lifespan than valves with a nonrising stem. Also known as bolted bonnets, their flanged stem housing bolts in place for easy disassembly during maintenance. However, the housing makes them larger and heavier than valves with a threaded or welded housing.
Full-port valves don’t restrict flow.
Standard-port valves slightly restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
